SK9428Y1 - Two-dimensionally curved aerodynamic winglet - Google Patents

Abstract

Two-dimensionally curved aerodynamic wings can be included in the field of aircraft and aviation and can be used in civil and military aviation. The two-dimensionally curved aerodynamic wings are placed on an aircraft (1) with wings (2), which are equipped with aerodynamic wings (3) and which have a floor plan in the form of a curved triangular surface towards the rear, this surface being simultaneously curved upwards in in the form of a continuous arch.

The field of technology

The technical solution concerns an aircraft wing with two-dimensional curved aerodynamic wings. The technical solution can be classified in the field of aircraft and aviation.

Current state of the art

Airplanes manufactured and used today often have winglets at the end of their wings. They are small auxiliary surfaces of various shapes at the end of the aircraft wing. They direct the air vortices that act on the ends of the wings. The consequence of this is reduced induced wing drag during flight, which causes reduced fuel consumption and thus greater range. Aerodynamic wings can also affect the characteristics of the aircraft during take-off, they can improve its controllability and reduce the noise of the machine. Nowadays, it is common for newer aircraft to mount aerodynamic wings on the wings. Despite the fact that aerodynamic ailerons minimize turbulence at the ends of the wings, their chosen shapes usually only slightly deviate from the dimensions (mainly the width) of the wings, which does not completely correspond to the wings observed in nature, which have the inductive resistance of the wings suppressed much more effectively. The issue of the application of aerodynamic wings is presented, for example, in the following literature and in patent documents: Literature:

The essence of the technical solution

The essence of the technical solution consists in the application of the solution of two-dimensional curved aerodynamic wings on the wing of the aircraft. These have a floor plan in the form of an arched triangular surface towards the back, and at the same time this surface is curved upwards in the form of a continuous arch. The solution makes it possible to reduce the induced resistance of the wings during the flight of the aircraft. The solution makes it possible to reduce the induced drag compared to wings with a conventional type of aerodynamic wings. The result is an increase in the utility, operational and flight characteristics of the entire machine with a relatively small investment.

Overview of images on drawings

In fig. 1 shows the overall layout of the functional parts of the proposed technical solution.

Implementation examples

In fig. 1 shows an example of the implementation of a technical solution. It shows the overall arrangement of the functional parts of the proposed mechanism. The technical solution consists of an aircraft 1 with wings 2, which are equipped with aerodynamic wings 3 and which have a floor plan in the form of an arched triangular surface towards the rear, and at the same time this surface is curved upwards in the form of a continuous arc.

The advantage of the proposed solution is a further reduction of the total induced resistance of the aircraft 1 by a reduction of the induced aerodynamic resistance of the wings 2 during flight, which will cause a further reduction in fuel consumption and thus an increase in range. Aerodynamic wings 3 increase their influence on the characteristics of the aircraft 1 during take-off, they can improve its controllability, reduce the noise of the machine and shorten its run-up at take-off. They suppress the turbulence at the ends of the aerodynamic wings 3, and thus reduce the probability of possible wing oscillations 2.

Industrial applicability

The device according to the proposed solution can be used in civil and military aviation and in all airplanes that have a classic and less common way of arranging the bearing surfaces.
